LOCK.

' 3 To all whom it may concern:

I, l; i m

sliding doors or to a slngle door and doorswinging lock.

Be it known that I, 'MELBOU'RNE' E. BLATCHLEY, a citizen of the United States, residing at Garden City, in the county of Finney and State of Kansas, have invented a new and useful Look, of which the following is a specification.

' This invention relates to improvements inlocks, the object of the invention being to 'is entirely avoided and the members of the lock are secured together in such a manner that they cannot be taken apart, thereby preventing loss of any of the parts of the With the foregoing and other objects in view, which will appear as the description proceeds, the invention consists in the novel featuresof construction and combination of parts which will be fully described'hereinafter and particularly pointed out in the claims.

In the drawing accompanying and formin part of this specification, L

F lgure 1 is a side elevation lllustratlng improved lock as applied to a pair of post; I v g V v Fig. 2 is a perspective view of the parts constituting the lock in unassembled condi tion; and

Fig. 3;is a perspective view of a modlfied form of the lock specially adapted for a single gate or swinging door. The same characters of reference designate the same parts in the different figures of the drawing.

In" he embodiment-of the-invention i11 s-' trated in Figs. 1 and 2, the reference numeral 2 designates a locking bolt provided at one end thereof with a depending leg 20 formed of angular cross section for a portion of its length adjacent to the bolt 2, as shown at 3, and of cylindrical cross section for the remainder of its length, as shown at 4. The leg is provided in the cylindrical Specification of Letters Patent. I

dlametrically through "said cylindrical por-j' portion thereof with an' opening 5 extending tion and extends in the direction of the length of thebolt 2. The bolt 2 is provided at the opposite end thereof with a second depending leg 8, preferably of angular cross section and adapted to engage with a simi larly formed opening '15 in a member 9, which may be driven into the door, or into' one of a pair of sliding doors. Ifdesired,

the shank of the member 9 may be screw threaded and screwed into the door, 'or,'if-

preferred, the shank may be in theform of a bolt and provided with a nut for securing it in the door. a

For cooperation with the depending leg passage of the lug 7 of the leg 20 through said opening. 'The shank of the socket member 10 may be secured to the door post in any of the ways set forth in connection with the member 9, or it may be provided" with a crosswise extending opening 13 adapted to permit the passage of a nail-'14- the door" tlierethrough after it is driven into ost. Y

When the lock above described is to be used for securingdouble doors together, the

depending leg 20-is first passed throughthe opening 11 in the socket member 10 and said" socket member turned on the cylindrical portion 4 of the leg to a position at, right angles to the bolt 2, so as to carry the lug 20 of'the bolt 2-, I provide a socket member 10 having an angular opening 11 and pro-j vided in one of the side walls of said open'' mg with a recess 12 adapted to permit the cured in the door and the socket member 10 in the door post or "a1nb. The-door locking position "of theparts 'is elean'y shown in Fig. l, in whichposition a padlock may be inserted through the opening 5"of the depending leg 20,.Tthereby preventing unauthorized removal of the locking leg 8 ter with diagonally opposite openings in the socket member 10, for permitting a car seal to be used.

In the form shown in Fig. 3, a locking bolt 19 having a single depending leg 16 identical in construction with the leg 20 of the bolt shown in Figs. 1 and 2 is provided. For cooperation with the leg 16 I provide a socket member 17 similar in construction with the member 10 shown in Fig. 2, excepting thatin this case the recess 18 for permitting the passage of the lug on the depending member 16 is formed in one of the corners of the angular opening in the member 17. In the use of this device, the member 17 is placed on the stem or leg 16 in the same manner as described in connection with the device shown in Figs. 1 and '2, the member 17 being then'turned so as to carry its recess 18 out of alinement with the lug or. the leg 16 and the socket member secured in the door or gate post in any of the ways above described, said socket member being located at such a point as to permit the bolt 19 to project beyond the door or gate post for engagement with any suitable locking socket carried by the door or gate, in which position a padlock may be engaged with the opening 21 in the leg 16. lVhen it is desired to open the door, after the removal of the padlock, the bolt 19 is raised so as to bring its cylindrical portion within the opening of the socket member 17 and at the same time raise the bolt 19 out of engagement with the socket member on the door or gate whereupon the door or gate is free to be swung open.

While I have described in detail the struc ture herein illustrated, it is to be understood that I do not thereby limit my invention to the precise features of construction shown, as I am aware that many mechanical changes may be made therein without departins from the spirit and scope of the invention as set forth in the appended claims.

Having thus described my invention, what I claim is:

1. A device of the class described, com prising a bolt, a depending leg carried thereby, a socket member having an opening for the reception of said leg, and a lug carried by said leg and projecting at right angles therefrom whereby the complete removal of said leg from the socket member is prevented.

2. A device of the class described, comprising a belt, a depending leg carried thereby, a lug formed on said leg and extending at right angles therefrom, a socket member having an opening adapted to receive said leg and a recess in one of the side walls of said opening adapted to permit the passage of said lug, the leg being formed at one portion of its length to prevent rotation thereof in said socket member and at another portion to permit such rotation and said lug being adapted to prevent the complete removal of said leg from the socket member after rotation thereof on the leg.

3. A device of the class described, comprising a bolt, a depending leg carried thereby, a lug formed on said leg and extending at right angles therefrom, a socket member having an opening adapted to receive said leg and a recess in one of the side Walls of said opening adapted to permit the passage of said lug, the leg being formed at one portion of its length to prevent rotation thereof in said socket member and at another portion to permit such rotation and,

of said lug, the leg being formed at one por' tion of its length to prevent rotation thereof.

in said socket .member and at another portion to permit such rotation and said lug being adapted 'to prevent the complete removal of said leg from' the socket member after rotation thereof on the leg, said socket and leg being provided with registering openings for permitting the passage of a sealing member.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
